YB1210R

300mA, Ultra-Low-Noise, High PSRR LDO Regulator

Description

The YB1210R is a series of ultra-low-noise, low dropout (LDO) linear regulators with 2.0% output voltage accuracy. The YB1210R regulators achieve a low 320mV dropout at 300mA load current of 3.3V output and are available in voltages ranging from 1.2V to 3.6V with 0.1 V per step (custom voltage is considerable at request).

The YB1210R regulators are optimized to work with low-ESR and low cost ceramic capacitors, reducing the amount of board space critical in portable devices. The YB1210R requires only 1.0μF output capacitor for stability with any load and consumes less than 1μA in shutdown mode.

Built-in thermal shutdown and short-circuit protect offer secure protection against fault operation. The YB1210R regulators are available in SOT-23 / SOT-25 / SOT-89 packages.

Note :

1.The drop out voltage varies depending on output voltage selection. Dropout is defined as VIN – VOUT when VOUT is 100mV below nominal VOUT where VIN = VOUT + 1V for nominal VOUT.

2.Time needed for VOUT to reach 90% of final value.

3.Time needed for VOUT to discharge below 0.5V.
